OpenStudy (anonymous):

@Hero ...... you're the smartest person I can think of :( haha could you help me out?

hero (hero):

The best way is to start with the answer choices

OpenStudy (anonymous):

So you mean guess?

hero (hero):

"Assume" not guess

OpenStudy (anonymous):

Like work backwards right?

hero (hero):

Precisely

hero (hero):

For example, Assume 829.79 is the cost of the In-Style Package.

hero (hero):

Then 3(829.79) is the cost of the Premier Package

OpenStudy (anonymous):

Ok, so that equals 2,489.37..

hero (hero):

plus the cost of the in-style package

OpenStudy (anonymous):

So that means..

OpenStudy (anonymous):

I'm sorry, as you can see I'm lost

hero (hero):

$2489.37 is the cost of the Premier Package. Now add the cost of the in-style package.

OpenStudy (anonymous):

3,319.16 ?

hero (hero):

Great, now add that to the msrp

OpenStudy (anonymous):

I got 32,221.27

hero (hero):

Multiply that by 0.065

OpenStudy (anonymous):

I got 2,094.38

hero (hero):

Add 32,221.27 + 2094.38

OpenStudy (anonymous):

it equals 34,315.65

hero (hero):

Which is not 34,290.08

hero (hero):

Follow that same process for the other three choices.

OpenStudy (anonymous):

got it, thank you!! you were so helpful

OpenStudy (anonymous):

hope I didn't take so much of your time

hero (hero):

Hardly

OpenStudy (anonymous):

None of them equaled 34,290.08 @Hero

hero (hero):

4(823.79) = 3295.16 28902.11 + 3295.16 = 32197.27 0.065(32197.27) = 2092.82 32197.27 + 2092.82 = ?

OpenStudy (anonymous):

34,290.09..

hero (hero):

Close enough

OpenStudy (anonymous):

So the cost of the In-Style Package is 823.79

hero (hero):

Correct
